An experiment was conducted to investigate the influence of evaluative factors upon preference for situational and dispositional attributions. Subjects listened to a tape recording of a group discussion on smoking, two actors presenting arguments in favour of smoking and two actors arguing against smoking. Subjects were then asked to explain in attributional terms the actors' behaviour and their own smoking behaviour, their evaluation of smoking being separately assessed. Results provided no support for a general self-other attributional difference; subjects did not explain their own behaviour in more situational terms while explaining the behaviour of others in more dispositional terms. Findings indicated that individuals generally attributed positively evaluated behaviour to dispositional factors and negatively evaluated behaviour to situational factors, regardless of attributor role (actor or observer). The results are interpreted as offering support for a positivity bias in attributional preference. 相似文献

Some evidence for a limited capacity parallel selfterminating process in simple visual search tasks.
A H van der Heijden 《Acta psychologica》1975,39(1):21-41
An experiment was carried out in order to investigate the questions of exhaustive vs selfterminating and serial vs parallel processing in a simple visual search task. In the experiment, 1, 2 or 3 letters were placed on an imaginary circle round the fixation point. Two different letters were used, one of which was defined as the ‘signal’. Ss had to respond ‘yes’ when one or more signals were in the display, ‘no’ otherwise. The number of signals in the display was varied from ‘no signals’ to ‘all signals’.A decrease in latencies with increasing number of signals for a fixed number of elements presented was observed indicating a selfterminating search. A decrease in latencies with increasing number of elements when only signals were presented was taken as evidence for a parallel selfterminating process. A further analysis of the error data showed that a limited capacity system had to be assumed. It was shown that it was possible to construct the overall pattern of latencies over conditions from the error data obtained. 相似文献

The purpose of this project was to determine if it is possible to predict from the information contained in the write-ups of the preliminary evaluations of patients accepted for Institute supervised analyses those patients who would successfully complete their analyses and those who would not. Three raters independently studied the write-ups of 183 cases treated at the Boston Institute during the period 1959-1966. Each rater filled out a questionnaire of 105 items which were thought to be of possible predictive value. Outcomes were sought from the analysts who treated the patients. 130 outcomes were obtained and revealed that the patients fell into 4 distinctly different outcome groups: (Group 1) those who completed analysis by mutual agreement between the analyst and patient; (Group 2) those who prematurely terminated their analyses against the advice of their analysts; (Group 3) those whose analyses were prematurely interrupted by their analysts; (Group 4) those whose analyses became interminable. Statistical analyses were done to see which of the 105 predictor items distinguished these four distinct outcome groups. Many of the predictor items were not useful because they either showed no variation among patients, or were too often left blank, or were rated with very low interrater agreement. Of the remaining items, we found ten items which did show a highly significant difference between Group 1 patients and those patients in at least one of the other three outcome groups. We found five other predictor items which showed large, although not quite statistically significant, differences between Group 1 and at least one of the other three groups. Of these 15 items, 7 dealt with family history. The others concerned the patient's past history (2), object relationships (2), patient's sex (1), symptomatic state (1), field of endeavour (1), and history of previous psychotherapy (1). We found it made no difference in terms of these 4 outcome groups what the patient's diagnosis was or whether he was a 1st, 2nd, 3rd or 4th supervised case. Among the other negative findings were patient's age and the ability to experience and tolerate felt anxiety. These did not distinguish any of the outcome groups. These findings show that additional predictively useful information is present in the preliminary evaluations of patients already screened and accepted for Institute analysis by trained evaluators. These results suggest that one particularly important area on which to focus future attention is family history. 相似文献

Right, mixed and left-handed college students were given the complete WAIS, and a series of cognitive factor tests. Results showed left- and mixed-handed individuals to have a significantly lower full scale I.Q. than right-handers. There was no difference between the mixed and left-handers. In all three handedness groups, subjects with a positive family history of sinistrality had a lower full scale I.Q. than did subjects without left-handed relatives. Neither handedness nor family history differentially affected the Verbal or Performance subscales, nor did they have a significant effect on scores in the other cognitive tests. These results are discussed with respect to Levy's theory of hemispheric specialization, and to the role of inheritance and brain damage in the causation of left- and mixed-handedness. 相似文献

Summary In this paper some implications of the pulse generator model of time perception have been tested. In the case of serial (re)production of an interval a lengthening effect occurs. Generally, this phenomenon is explained by assuming that the time-keeper is driven by the state of general physiological activation which decreases in the course of the task. An experiment was carried out in which EEG activity was recorded during the time estimation process. It appeared that a lengthening effect occurred, but there was no correlation between the reproduction times and the means of the EEG spectra, however. In a second experiment two series of time estimations were compared as a function of administering a placebo and methamphetamine. In the latter case the model predicts that no lengthening will occur since arousal (at least for a short period of time) is kept at a high and constant level. In fact, no differences between the regressions of the time estimation curves before and after drug administration have been found, so that the predictions of the model as regards the origin of lengthening could not be supported. It is suggested that the nature of the effect should be studied within the framework of the cognitive theory of time experience which offers various starting points in this respect. 相似文献

The relation of fusion hertz to the number of pulses in a train was explored under three conditions: monoptically, dichoptically inphase, and dichoptically antiphase. All three conditions show an increase in fusion hertz as the number of pulses in the stimulating train increases. Over the range of pulse numbers investigated, fusion hertz varies principally with the number of pulses delivered to one eye regardless of the stimulating condition of the other eye. 相似文献

Sequence influence on the organization of meaningless serial stimuli: economy after all 总被引:1,自引:0,他引:1

This article provides evidence for an extension of structural information theory, a theory which describes perceptual organization formally, into a more general theory of representation that takes the role of organizations obtained earlier into account. In eight experiments, subjects study series of colored dots. Each series contained 6-8 dots of different colors, and viewing time was between 400 ms and 60 s. In several experimental procedures, subjects recalled the series presented. The experiments systematically varied the economy of the organizations of the series as described by structural information theory as well as a number of aspects of the context in which the series were presented, like order of presentation of a series, order between the series, viewing span, viewing time, and recall procedure. Recall was influenced both by the economy as well as by the context. It is shown how the context influences the relative strength of the most economical organization as compared with rival, local organizations. A structured network model is presented that accounts for the influence of both the economy and the context. 相似文献
